Conduit Connection and Grounding Instructions - For Enclosures Not Prepared with Conduit Entry Holes
NOTES:
- Use of a UL Listed liquid-tight hub or connector fitting is required to maintain NEMA 4X, 12 or IP69K Rating.
- Use of a UL Listed hub or grounding bushing system is required for metallic grounding applications ¾" max.
- Grounding bushings are not required with non-metallic conduit.
1. Conduit Holes – cut holes in enclosure at drill point locations only. Drill points are provided as a guide. See Fig. 6 for DS and Fig. 7 for CDS details.
Use of a standard hole saw is the preferred method.
2. Conduit Connections
a. Metallic – secure the conduit hub onto the conduit. Then secure the conduit hub into a prepared enclosure hole using the hub nut and/or
grounding bushing inside the enclosure. Use the wiring diagram illustrated on the Wiring Instructions. Phase conductors and separate equipment
grounding conductor (if present) should be sized in accordance with N.E.C. FOLLOW GROUNDING INSTRUCTIONS BELOW
b. Non-Metallic Conduit – secure conduit to the conduit connector (hub) either before or after the conduit connector is secured into an enclosure hole
using the connector locknut. Use the wiring diagram illustrated on the Wiring Instructions. Size phase conductors and separate equipment ground to
N.E.C. FOLLOW GROUNDING INSTRUCTIONS BELOW
Grounding Instructions
IF A METALLIC CONDUIT SYSTEM IS USED TO PROVIDE THE
EQUIPMENT GROUND:
Metal conduit fittings with a ground screw on lock nut/bushing must
be utilized (not provided). Attach a properly sized ground wire (not
provided) to each ground nut/bushing screw. Secure the opposite
ends of the wire to a terminal on the green/yellow ground block
(provided on metal din rail). NOTE: Only one wire per terminal of
ground block. The "jumper" wires and ground block complete the
grounding path.
IF A SEPARATE EQUIPMENT GROUNDING CONDUCTOR IN
THE CONDUIT IS USED:
Connect the grounding conductor to the green/yellow ground block
mounted on the metal din rail. NOTE: Only one wire per terminal of
ground block.
SHORT CIRCUIT PROTECTION ACCORDING TO UL
These units are suitable for use on circuits capable of delivering not
